The NFL is just three weeks old, but Aaron Rodgers, Andy Dalton, and Cam Newton are up, while Andrew Luck and Colin Kaepernick are not.

Using two different advanced stats and a metric from fantasy football, we came up with a formula to rank all 32 NFL starters.

The formula uses Football Outsiders' DYAR metric, ESPN's total QBR metric, and the percentage of teams that own each quarterback in ESPN's Fantasy Football game. Think of the latter as a job-approval rating, an indication of how fans think of each quarterback's potential moving forward.

In the case of injuries, we will continue to rank the injured starter unless he is out for the rest of the season or there is doubt about his role once healthy.

1. Aaron Rodgers, Green Bay Packers

One thing to know: Not all the advanced stats loved Rodgers' five-touchdown, zero-interception win, with Pro Football Focus giving it a slightly below-average grade. But the numbers used here liked it enough to vault Rodgers up to the new No. 1 from No. 3 last week.

3. Ben Roethlisberger, Pittsburgh Steelers

One thing to know: Roethlisberger slips from No. 1 thanks in large part to suffering a knee injury that knocked him out of his past week's game. He avoided serious injury, however, and will be back this season.

10. Russell Wilson, Seattle Seahawks

One thing to know: Wilson played well considering Marshawn Lynch was out most of the game. But the 26-0 shutout of the Bears was more about Chicago's awful offense (the Bears punted on every possession!) and the return of Kam Chancellor on Seattle's defense.

14. Marcus Mariota, Tennessee Titans

One thing to know: Mariota is on pace to throw 43 touchdowns this season, and John Glennon says the Titans are "far better on the offensive side of the ball" this season than they were at the same point last year.

18. Joe Flacco, Baltimore Ravens

One thing to know:Jeff Zrebiec says Flacco sounds like a player challenging his teammates when he says "make sure that we want to go out there and win a football game." And then, "we're not believing in ourselves enough and we're not envisioning winning those football games."

19. Matthew Stafford, Detroit Lions

One thing to know:Drew Sharp writes that time is "running out" for Stafford: "Even though he hasn't proven himself a 'franchise quarterback,' he must immediately act like one in demanding dramatic philosophical changes in the Lions' offensive strategy. If that brands him a prima donna, so be it."

21. Ryan Tannehill, Miami Dolphins

One thing to know:Adam H. Beasley says Tannehill "needs help," noting that he hasn't proved to be a quarterback "who can consistently rise up when everything around him crumbles, as has been the case this young season."

24. Kirk Cousins, Washington Redskins

One thing to know:Sally Jenkins says there are reasons to be bullish on Cousins, writing, "Cure his interception issues, and you've got a smart, mobile quarterback who gives you good third-down consistency, avoids sacks, and has a near 70-percent completion rate." Of course, "curing" a quarterback's interception issues is often easier said than done.

28. Ryan Fitzpatrick, New York Jets

One thing to know:Brian Costello says Jets fans finally met "the bad Ryan Fitzpatrick on Sunday," but he noted that even though Fitzpatrick is inconsistent, "there is no reason to start calling for Geno Smith."

30. Ryan Mallett, Houston Texans

One thing to know:​Coach Bill O'Brien on Mallett's Week 3 performance: "I think that there are certainly things to improve on, but I thought he managed the game better. I think he got us into the right play better. I thought his mechanics were better. He was tighter in the pocket. He was a bit more accurate. He completed more balls."

32. Alex Smith, Kansas City Chiefs

One thing to know: Poor Alex Smith. Playing a night game in Green Bay is already a hard enough task. But he had the added pressure of being constantly reminded that he was the top pick of the 2005 draft when the 49ers passed on Aaron Rodgers, something Rodgers hasn't forgotten.

Now check out how many of these quarterbacks are among the highest paid.
